Connection ArduinoNano (ESP8266) -> Blynk fails

Hi,

I use a Aduino Nano with an ESP8266. The attached sketch worked before, but fails to work now.
The terminal output shows that the msg [02|00|01|00] is repeated. The blynk app on my iPhone show the Arduino is offline.
What do I have to change?

void loop() {

Hi,

it was solved by simply restarting my router.
